These coils are sometimes several hundred feet in length and not only must be supported every few feet, but in such a way as to allow forexpansion and. contrac- -ers, each comprises essentially a hanger plate lOand a susper'ision arm 11. The plates -1 0 are preferably stamped from a strip of sheetmetal angular-1y cut ofi 1 from a strip of,stock as shown zit-12s tion.

These apertures'are spaced apartthesame distance as thepipes of the coil and are pref-- erably located near the outer edge of the hanger plate and made of slightly greats diameter than the diameter of thepipes. It

is necessary as heretofore stated that-the 1 pipe coils be spaced slightly away from the wall so as to permit free passage of air between-the pipe and the wall while at the same time it is advisable to' have the edge of the hanger plates ahiit against the walL' The manner'of arranging the apertures and hanger then attains these objects and in ad dition the hanger .plates do not project into the room any farther than is necessary is well known. one member'of .a-p pe coil isfv liable to become? heated j soonjer than the;
